Thanks again for your helpful reply. I have a Brother All-in-One Duplex MFC-8910DW with fax, scan & copy, & it does require Brother s/w to do all the functions beyond simple print & copy (which both work fine now). But all the other functions like scan & fax, etc., require Brother-provided s/w. I went to the Brother website to try to get a 64 bit upgrade, but there is none. S/w I have is latest available.
All of my TurboTax Premier copies of prior years’ filings will not open with Catalina & desktop icons of them do not display as they should, indicating a s/w problem of some kind. I desperately need access to the prior year (2020) s/w copy of filing on my iMac to do this year’s taxes because this s/w copy contains many pages of depreciation items which normally will fill in on the current year s/w but won’t even open with Catalina. I suspect this may be due to the Word s/w that won’t work with Catalina, but I’m only guessing that as a possible problem.
Bottom Line: (1) printer functions beyond copy & print don’t work w/Catalina (2) prior year filed tax s/w copy on my iMac is needed for fill-in for this year’s taxes (many, many pgs. of detailed depreciation schedules-way too many to insert by hand) prevent me from doing this year’s taxes either online or from 2021 TurboTax CD with Catalina.
I believe I have no choice but to downgrade to Mojave from Catalina, a formidable task!
What I think I need is advice on how to do that so all printer functions, all MS Office Suite ( Word, Excel, etc.) & all tax s/w will work again.
