After you file

if what you reported is correct, you are not getting a refund.  your tax liability was more than your withholding and estimated tax payments. you need to pay the IRS $215 on or before 4/15/2021. you can either send in form 1040-V with a check. make sure to read TT filing instructions for what must be on the check to avoid issues. you also have the option of using IRS website - Direct Pay to pay through your checking a/c  (free) or debit or credit card.  if you pay by mail use a tracking method.
