What should I do if I have withholdings from two states but a portion of the withholdings from one of the states is invalid?

My employer is based on California.  I worked for them remotely from Ohio until June before I moved to California permanently.

I was double taxed on the the income I made while living in Ohio from Jan-June. Based on my research, I do in fact owe that tax to both states, and there's a tax credit for Ohio called "Taxes paid to other states" that I can use to reduce how much I owe.

However, from July through November, I had my Ohio address in Workday (this was my fault for not updating it), so my employer was withholding both Ohio and California, even though I "should" have only been withholding CA.

What can I do here?  I'm not sure how to get a corrected W-2 from my employer because it was generated on Workday based off my payslips which were generated each month based on my incorrect address.  Is there anything I can do in TurboTax to get this filed correctly?

copies of the W-2's go to the states so no matter what you do in TT if that's different from what's on the W-2's your returns will get kicked out by their computers and you will get notices adjusting from what you show to what's on the w-2's. states also get info from other states if you claim credit for double taxation so even Ca may issue you a notice.  could you write back to the states after you get them and explain what happened?  maybe CA will because you'll be claiming less of a credit but certainly not Ohio. they will want corrected w-2 from your employer.  so contact your employer and see what they'll do. if Workday is the "employer" shown on the W-2 and your employer says to contact them ask for their phone number    

also TT accuracy guarantee may be void.

You do not owe tax to Ohio for the income earned after you moved. 

You cannot claim a credit on the Ohio return for tax you paid to CA.

You can claim a refund of the over withheld Ohio tax. 

Ohio does a convoluted tax calculation for part year residents. It calculates tax on total income, then it calculates a part year resident credit, which it subtracts from the tax it calculated on the total income. The credit is calculated as your non-Ohio income divided by Total adjusted Income multiplied by the total tax. TurboTax (TT)   does this by allocating your income as either Ohio or non-Ohio. W-2 income will be allocated by the state name abbreviation shown in box 15 of your W-2. TT will ask you, item by item, in the state section, how much of your other income is Ohio or non-Ohio income. Make sure that your non-Ohio wages show CA (Other state postal abbreviation)  in box 15 of your W-2 screen, with the CA amount in box 16.

Be advised that you will probably have to use a work around to get TT to prepare the return to get you your refund. At the w-2 screen split the boxes 15-20 W-2 info into 2 lines. On the 1st line leave OH in box 15 but change the amount in  box 16 to the amount you earned while living in OH; leave the OH withholding in box 17. On the 2nd line with CA abbreviation in box 15, increase the state wages amount in box 16; by the amount you reduced the OH box 16. Don't change the CA withholding in box 17 (even if  blank or 0)
