Exact same issue as others have reported for several years, here. TT pulls in random, wrong numbers from the TT 2021 return that I successfully filed and am now looking to "amend" in TT. The refund monitor goes to a random $8,895 tax due instead of $0 before I enter any changes.
This is just one more of the dozens of know, multi-year-old malfunctions of TurboTax that Intuit is ignoring while advertising their "no mistakes guarantee." The IRS rejects TT submissions because the TT software mal functions, spitting out wrong numbers. The same applies for depreciation calculation issues, foreign tax credit calculation and submission issues, home office classification issues... and so on. The list is very long.
Interestingly, my own experience and that reported of numerous customers (including is this thread) is that the customer service reps often just hang up on you or claim no longer to be able to hear you when these issues are brought up. It might be a Intuit procedure to deal with these hairy, known product defects.
