Thank you, RangiKeen! Your solution was just what I needed to do.
I'm on a newer computer than I used for TT Online last year; Mac M4 Pro running v15.3. After logging in to begin my 2024 return, TT recognized me, but when it tried to populate my prior return a page appeared with "Oops, something has gone wrong. Please try again." After fruitless repeated attempted over the course of days, I gave up and called TT support. The woman who tried to help me for almost two hours was great (truly was trying to help me), but she couldn't figure out what was "blocking" TT from loading my data. I was about to resort to using TT Desktop, but found your post and thought it makes sense that Apple's newer OS isn't working with TT. (Someone needs to fix that.... Apple or TT.)
As you recommended, I moved my old TT files to a different location on my laptop, opened TT and it let me right into "Personal Taxes." Then I moved my tax files back, clicked on "Documents" in TT and all my past years were there. I started my new tax return and all the data from 2023 populated.
I've since completed my return (have not filed yet) and all worked perfectly, just as it has in prior years. Big thumbs up to you for solving my TT problem! Thank you and to everyone who contributed to this post.
