Get your taxes done using TurboTax

None of "the IRS owes it to me" matters if you let your BF claim the kids.  Your children cannot be claimed on two 2020 tax returns.    If you let BF claim them, you lose.  He will get a small tax credit to lower his own tax bill and you will get no stimulus money for the kids.  None.
