PS its interesting At least for me it shows that if you have T3 with content in 21 it should change what you owe/refund number independent of whether you have something in 52/53. if you set 21 to 0 and nothing in 52/53 it should increase refund and decrease what one owes
However, it seems if you delete 21 in something that has no 52/53 in the original T3 it does not change in turbotax whether you delete value in 21. But as soon as you add a value into 52/53 it changes the same amount whether you artificially deleted the value in 21 or left it in.
I get that whether I change the values through the form or easy step
That suggests that turbotax assumes that every T3 with a value in 21 also has a value in 52/53
and so really makes its judgments based on 52/53 not 21.
It also means you have to add a value into 52/53 that is not in the original T3, which I find problematic as it changes the validity of the slips if I have to add artificially values in turbotax that are not in the original slip.
