unless either or both of you are over 55, the combined maximum HSA contribution for 2021 was $7200 split any way you want. you had until the due date of the return 4/18/2022 to withdraw the excess contribution and earnings thereon. since you apparently didn't you will owe a penalty of 6% on the $600 excess contribution maybe less depending on the HSA balances on 12/31/2021 taking into account 2021 contributions made in 2022. no amended return should be needed. the Turbotax return should have included the penalty.
the max HSA contribution for a married couple in 2022 is $7300 so with a $600 excess carryover you should limit your contributions to $6700. contribute more and you'll be subject to an excess contribution penalty again in 2022 and every year thereafter until the excess is eliminated.
