I checked over my federal returns and all my state returns, and it looks like my total income is the same for all returns. The amount on my IL 1040 box 9 is equal to both my state wages total plus income from interest. It also looks like the portion that I designated as VT income is the same for the IL and VT returns.
Could you please clarify what you mean by "the error is coming from you taking the tax credit for taxes paid to VT"? It looks like the tax credit is recorded on my IL return, and all the numbers match the federal return and the VT return before the tax credit is applied.
I do have a bit of a unique situation though. I have 4 W-2's. One is from a Vermont company that I worked for in Vermont. One is from an Illinois company that I worked for in Illinois. The other two are from a Vermont company that I worked for remotely out of Illinois. One of these W-2's from this company is for Vermont, and it has nothing in boxes 1-6. The other W-2 is for Illinois and boxes 1-6 are filled out with all my income for this company. I think I filled everything out correctly despite this odd situation, but it might be the cause of my issue.
