You will need to amend your return.
You will need to wait until the IRS has accepted your return and you have received your refund before you file an amended return.
You will need to complete a nonresident return and print it and attach it to your amended return (1040X)
TurboTax does not support nonresident returns.
However we have a partnership with Sprintax offering a nonresident tax filing solution to our TurboTax customers.
Visit the TurboTax/Sprintax site for more info or to get started.
You can print out the 2018 1040X on the IRS website. You should not prepare the amended return in TurboTax. The links to the 1040X are located below.
You can use the steps here below to amend your 1040 return, after the IRS has accepted your return and you've received a refund (or pay tax due). Once you prepare your amended return, you will need to mail it in with your 1040NR attached , as amended returns cannot be e-filed. So follow the steps here below to help you fix this situation.
**Make sure you check the box to show the tax year that you are amending on Form 1040X.
Per IRS page 5 (https://www.irs.gov/pub/irs-pdf/i1040x.pdf:(
