@mdwill01 Yes this is worded terribly. My 2020 box 17 was unchecked, but I interpreted it the other way, in that you just put in the Line 17 number which I did. I then populated the Line 18 number as instructed, and then put in the Line 17 number a second time as instructed.
I also thought it was very odd that it asked you for the exact same number twice, but I was able to file and when I reviewed the form it looked like all of this data came through correctly.
