when there's an excess there are two important dates
4/15/2024 was the latest date you could take out any excess without penalty if your return was not extended. In addition, any earnings on the excess would have needed to be withdrawn and would be taxable in 2024 - you'll get a 1099-SA if the funds are withdrawn.
if you did not extend the return, you owe a 6% penalty on the excess or FMV of account if less (Turbotax will calculate this with the proper entries). the excess can no longer be withdrawn to avoid the penalty. in 2024, undercontribute to avoid another year of penalties for excess contributions. this penalty will recur every year until the excess is corrected
if you did extend then you have until 10/15/2024 to withdraw the excess and earnings, if any, without penalty. The income, if any, would be taxable in 2024. Here you have the option of leaving the excess in and pay the 6% penalty, then like above undercontribute for 2024 to avoid the recurring excess contribution penalty.
