Why does turbo tax say I owe $840 i paid twice Still tells me I owe

[DoninGA]

If you are referring to the Tax Home web page in TurboTax where it shows the amount of your tax refund or the amount of the taxes owed, those numbers do not change.  TurboTax receives no information concerning whether or not a tax refund was received or the taxes owed were paid.

Why does my TT account say I still owe tax due?

TT does not update after your return has been accepted.  Your account will always show the result of the return you prepared using the software.  TurboTax never knows if you received your refund —or how, when or even if you paid tax due.  Your proof that you paid your tax will be your own bank/credit card records.
