Get your taxes done using TurboTax

I have filed my federal taxes, but have not paid yet.  The reason I owed is because of the advance premium tax credit.   So when I finished my taxes in March, TT said I could file and see what IRS does or wait.   So I waited, then turbo tax did an update and that message went away, said I was good to file, this was at end of March, so I did file.    Then just recently when into Turbo Tax it updated again, and now I am receiving a refund, due to them waving owed aca.   It seems silly to pay in May, if they are going to turn around a give it back to me?  Should I pay since I filed that I owed?  Obviously if I receive something before May 17 then we are good.  Suggestions?
