How do I Pay a 2019 1099-R This Year (2020)?

I have a 2019 1099-R from Vanguard as I am currently doing my 2019 taxes. Vanguard advised me to withdraw that amount because I had over-contributed due to income limits. I didn't realize my income was going to be as high as it was. TT says I might need to amend my 2018 return which I don't want to do because I'll have to refile with the state and city. Beyond that, I thought the extra money I earned in 2018 was going to be a one time event but I got a new job and now my new income is above the threshold so I also need to withdraw the first few contributions I made at the beginning of 2020. How can I pay the amount I'm going to withdraw for 2020 contributions in addition to the amount below from the 2019 1099-R on this year's (2019) tax return?  I just want to be done with this mess.
