My wife and I were both residents of the State of Maryland for all 12 months of 2021 and filed a Maryland resident joint return. I retired on 12/31/2021 and we were full time residents of the State of South Carolina for all 12 months of 2022. I received a 2022 W2 from my former employer for my last paycheck which included a lump sum leave payout. My payroll provider deducted taxes for the State of Maryland even though I was a resident of South Carolina starting 1/1/2022. My wife works remotely in South Carolina for a business located in the State of Maryland. She does not travel to Maryland for work or provides any services in the State of Maryland. Her payroll company deducted income taxes for the State of Maryland for the first 3 months of 2022. When I completed my 2022 Non Resident Maryland State return, I attempted to check the box for "Maryland Taxes withheld in error" but during the error check process, the Turbo Tax software instructed me NOT to check this box. I allocated all 2022 income earned to the State of South Carolina for my resident return and zero income to the State of Maryland for my Non resident return. I believe I should have checked the box for "Maryland Taxes withheld in error" and followed the Form 505 instruction 4. I am due a large refund from the State of Maryland for the 2022 income taxes that were withheld. My Maryland return has been sitting in the "still processing" stage for longer then expected and I have not received my refund. Can you please advise?
