Obamacare 2021 Income Overage

I was on Obamacare for three months in 2021.  My income went over the maximum amount to receive a subsidy, and now Turbo Tax is stating I must repay 100% of the subsidy I received.  Two questions:  (1) I thought Obamacare overages were forgiven in 2020.  Was this exemption not continued in 2021?  Also, (2) Income levels to qualify for a subsidy increased substantially in 2022, with a sliding scale for having to repay the subsidy.  Is there no allowance for either of these situations in 2021?
