My prior year (2018) state tax payment actual filled amount is incorrectly showing in turbotax schedule A while calculating the itemized amount, how to correct this?

I didn't filed 2018 state tax return through turbotax.

Is it showing your 2018 tax refund?  (From your Form 1099G)  Or perhaps your 2019 state income tax paid (from your Form W-2 and estimates entered?  

On Schedule A I would expect to see your 2019 withholdings and payments, information that comes from your W-2 and other entries and not your 2018 tax return but I am not certain if that is what you are seeing. 

If you could share a little more information about exactly where you see the information in the program this could help us to troubleshoot (or explain) a little better!
