look at schedule SE part III. I think Turbotax did a very poor job of informing taxpayers with self-employment tax how answering certain questions would affect their taxes. without realizing it you probably requested that a portion of your SE tax not be paid with the 2020 return but rather 50% of the deferral be paid by 12/31/2021 and the other 1/2 by 12/31/2022
