Capital Loss Carryover from 2020
In 2020, I had a total capital loss of $7477 (all short term) and used $3000 on the 2020 returns (the -$3000 correctly shows on line 7 on the 2020 Turbo Tax returns).
On my 2021 returns, I have a short-term loss of -$13 and a long-term gain of $17,484. I had assumed that I would be able to offset this gain with a $3000 loss carryover from 2020 plus the $13 short-term loss. However, TT is showing on line 7 a gain in the amount of $12,994 which means that the entire carryover of $4477 was used in addition to the $13 loss.
I do not understand why I am not limited to a $3000 capital loss carryover? Why is TT allowing the entire carryover amount to be used?
