I don't have a "recently deleted" folder in Photos on my macbook pro

Which version of Photos and MacOS X are you using?

I selected and deleted all the photos I wanted to, but a "recently deleted" folder didn't show up in my sidebar.

A recently Deleted album will appear in the sidebar, if you really deleted photos and not just removed them from an album. If you used the delete key while viewing a album, the photos will not have been deleted, but just removed from the album.You will still see the photos in the moments in the Photos view. To delete photos while viewing an album use the key combination ⌘⌫, not just ⌫.

In Photos 1.0 in Yosemite the recently Deleted album is hidden. You will have to reveal it with command "File > Show Recently Deleted". If the system version is El Capitan or newer, the recently Deleted Album will always be visible, if it is not empty.

Deleting Photos from a Photos 4 Library

1 - regardless of where you are in the library, i.e. Moments, Collections, albums, smart albums or projects, select the photo(s) you want to delete and use the key combination of Command+Delete to move the photos to the Recently Deleted smart album.

2 - click on the Recently Deleted smart albums in the sidebar.

NOTE 1: If you're using Photos 1.2 or earlier use the File ➙ Show Recently Deleted menu option.

3 - in the Recently Deleted album you can opt to let the photo automatically delete after the 30 day waiting period is up, delete them immediately or restore them to the library.

NOTE 2: deleting a photo from an album, slideshow, book, etc., with the Delete key only deletes the photo from that item. There is no key combination that will delete a photo from a project and move it directly to the Recently Deleted smart album.

NOTE 3: deleting a photo from a Moment or Collection (the Photos window) or the All Photos window deletes ALL occurences of that photo in the library.

Yes, we are on the same page. There were deleted photos in there and there was no smart album. I ended up shutting the computer down and when I came back later and deleted more, then the folder re-appeared. So fixed for now.

For others, I also was able to find them, indirectly, via View>library>recently deleted ^6

I would not feel comfortable with anything from Wondershare; you can do a search and find various references to the fact that the company sometimes includes some dubious software (malware or adware). I would not recommend it.

I have this same issue. My "Recently deleted" album has disappeared, even when I have things in it. My software is up to date (High Sierra 10.13.6) and I am on Photos v3.0. Please advise.

Moreover, you can try with this Recoverit for Mac, easily recover deleted photos from Mac Photos App
