Deductions & credits

It turns out that I had put in $2250 into my HSA for 2020. I used the $ number that Turbotax calculated/recommended as the maximum allowable amount that I can add to my HSA in 2020 (part of the year on high deductible health plan and the rest on medicare).  So I am not sure why Turbotax  for 2021 taxes now wants me to take out the money from the HSA or I would owe a 6% tax.
