I wish it were so!
My Form 8606 shows a conversion on lines 8 + 16 of 1$4000 in 2020, which is correct.
Since I can only convert $7000 for 2020, line 18 shows a taxable amount of $7000.
(If I override that to 0, my Federal Tax Due goes down, so TT -- and the IRS -- see that distribution as income.)
