After you file

No one at TurboTax knows if you paid the IRS when you filed your 2017 tax return.  Do you have bank/credit card records to show that you paid?  That is a large amount of money that you would certainly notice if you paid it--or did not.

What does the IRS say about why you owe?  Did they change something on your 2017 return?  Was there income that you did not include on that return?
