Amend will not be available until the IRS releases Form 1040X. We expect the form to be available in TurboTax in mid to late March. You do not amend until your original return has been processed. When you start your amend, TurboTax will show your refund amount as zero. Then that amount may change as you amend your entries.
When amend is ready, go into TurboTax and follow the instructions for amend. You will correct your W-2 in the amendt in the federal section, then walk through all of the amend questions to be sure the information carries to the state. You will amending both the federal and the state returns with the corrected W-2.
You have 3 years from the date you filed your return or 2 years after you paid the tax due (whichever is later) to file an amendment.
It appears the info you submitted to State of R>I is incorrect. You showed 44,000 plus of out os state income and I only had $2738. You also used the $10,200 unemployment exemption and RI is not allowing it. The entire return is not right.
