Why does TT give an error message about 1202 exclusion percentage? My 1099-DIV has $0.00 in Box 2c. So there is nothing to exclude, yet there' no option to disregard.

After downloading my 1099-DIV from Vanguard, TT error indicated "We found something wrong with your return."  There were choices for 50%, 60%, 75% or 100%.  How do you fix this so there's no error?
