Deductions & credits
You need a resident Colorado resident return and a non-resident Wisconsin return. Report the sale on your federal return and prepare the non-resident WI return before you complete the resident (CO) return. TurboTax will ask you what income belongs to WI; choose only the capital gain from the sale of the home. Colorado will tax all of your income, but you will be able to take a credit for any tax paid to WI.
Using the instructions, linked below, enter all estimated tax payments you made on your federal return. TurboTax will apply them to your state return(s). Choose State estimated taxes for 2024, then enter the state, amount and date you made the payments.
