as of this day, 2023-04-12 I am running the latest, updated TT home and bus. I used the IRS Pub 590a worksheets 2-1 and 2-2. Yes, I correctly entered my IRA to Roth conversion on 2-1 line 2 and the 1040 line 11. On Pub 590 WS 2-1 lines 4 thru 9 are ALL 0. I'm married and so line 11 is 214000. this correctly figures my roth magi. I carry that to Pub 509 WS 2-2 line 1 and on line 2 enter the much larger 204000. Because my taxible compensation is 2890 then this form results on line 11 of 2890. BUT BUT BUT on the TT worsheet the Roth IRA contribution limit worksheet line 1 is way wrong. it is almost 1/2 of my Pub 590 roth magi. The result of this error is that the Roth contribution I want to send NOW is reduced a lot from what the Pub 590 WS show as 2890!!! Something is STILL not correct with TT. And it is getting REALLY LATE to get it fixed so I can put in the correct numbers and send my FULL contribution to my Roth fund.
