Using H&R Block tax software With macOS Monterey v. 12.7.6 problems

I used TurboTax in past but “forced” to use H&R Block this year due to my late 2015 iMac not able to update O.S. & T.Tax requires v 13.0 or higher but H&R can wk with v 12 & higher.

Issue1. No red dot in upper L of window?!

To close window, must close program via R click dock icon or Apple menu.

2. (Main issue)

Cannot import my PW protected prior year T.Tax file.

Will not accept my PW (which I am 100% sure is typed correctly!)

Work-a-round I used: I opened the prior year TT file (had to use my PW, which of course worked with T.Tax)

Next, duplicate that file & then change PW to no PW.

Now H&R B. Was able to import the old TT file which was NOT PW protected.

I saved the new H&R file & then PW protected it & now H&R Block will not accept the H&R file PW!

To test I did the following:

Created new Tax return H&R file (with nothing in it) “Test #1 & used PW “123”

Quit H&R & reopened & when it asked for PW, I typed 123 & it worked!

Created another new Tax return H&R file (with nothing in it) “Test #2 & used my desired, long PW. Same problem, H&R Block will not accept this PW!

I am on the phone with H&R Block software support & after ½ hr. They have no answers to either the red dot question or the more important PW question! I asked them if there is some PW criteria such as must not be longer than a certain number of characters. Phone rep does not know.

Any help is appreciated.

(I know I can just not PW protect my Tax file but hate to do that once I enter my info. I know I can spend $$$$$ top buy a new Mac & I eventually will do that but not yet.)
