Not sure why my question is truncated. Here it is again: My spouse and I had filed taxes for 2019 as married filing jointly and applied a part refund of $3000 towards 2020 federal tax. We now file separately as head of household and single for 2020 after our divorce. How much of the 2019 refund shall each of us apply to our 2020 federal tax return? Do we apportion it equally?
