I am Washington state resident, when I filed tax return 2017 early of the year, I did not realize I can use sale tax in place of state tax. Because Washington state has no state tax, so I just left that blank. I used TurboTax online preparing and filing the return.
Now I am using TurboTax online to amend the tax return 2017, but it is not clear to me how to do that. I come to "Income tax paid" section, but none of the items out there looks right.
Please help.
