I now see online the reason that they changed the amount. They disallowed the amount of money that I reversed as an RMD in 2020. Per Fidelity I should not be paying taxes on this amount but the IRS begs to differ. They say I 'contributed' too much because of the reversal. I tried the solution of deleting the 1099-R and manually re-entering it and made sure I said none of it was an RMD and it still wants to claim that the reversed amount that was 'contributed' in 2020 is too high and therefore ineligible for a cotnribution so it is taxed. This reduced by refund by over $1000. Solutions anyone???
