Where can I get help when the state says my TurboTax amended return has an error?

[SweetieJean]

Which state, which tax year, and what type of error?

2020 Amended Missouri State tax.

Form MO-A, 2020 individual tax adjustments 

This form was populated by TurboTax when we filed the Amended Federal return, so we don’t understand why it is in error.

Sounds like you posted that $1,698 amount twice: once as withholding, and again as amount paid with your original return.
