Deleted Windows but Macintosh HD's volume reduced

I just deleted Windows on my iMac through Boot Camp but the Macintosh HD's volume was reduced and there is a new partition (Macintosh HD and Macintosh HD - Data). From 1 TB to 400 GB. I tried to use First Aid option, restarted my iMac but nothing has changed. Any ideas?

iMac 27" 5K, macOS 10.15

Boot Camp problem I have macbook pro mid12 with Mojave operating system on it. I have a space of 500 GB, around 120 GB was partitioned by bootcamp to install windows 10, now I was trying to uninstall windows 10 using bootcamp again, but i received the below message that "your disk couldn't be restored to a single partition". Then when I opened the Disk Utility, I found that it reads only one partition, the 380 GB for Macintosh, and the 120 GB disappeared. I used terminal to make if the space is there using "diskutil list" and I found that it only reads the 380 GB space and nothing appears about the 120 GB space as you can see below. Can anyone assist me to solve this problem?... Thanks in advance!

Problem after deleting partition I made a 750GB boot camp partition. Manually. Something went wrong when I tried to install Windows. I thought I would just delete the partition and do a new one and start over. I actually have 3.11 TB. I deleted them. How can I manage to make Macintosh HD, my "normal" partition completely large again, or make a new partition that is 750GB in size? Oh yes and where are my 750GB? : D

From macOS Terminal, post the output of

diskutil list

diskutil apfs list

Also, see About the read-only system volume in macOS Catalina - Apple Support for differences between the two 'Macintosh HD' parts.

SOLVED! I just needed to configure the partition through Disk Utility -> Partition.

I didn't know that, thanks! But anyways, my HD lacks 600 GB. I had 400 GB at Macintosh and 600 GB at Windows partition before deleting it.
