Last year I had two K-1s that I input manually. This year they can both be imported.
The first one combined the data for 2020 with the data from 2019 so I still have my carry-forwards.
The second import created a new K-1 so I have to either enter the new data with the 2019 shell or enter the 2019 data in the 2020 import. How do I choose which one to use so that when I do 2021 the new data will be combined with the 2020 data? (so I'm less likely to mess things up.)
