I am confused with form 2210AI Turbo Tax Deluxe Federal. Should each line 1 column contain income for that quarter or accumulated up to end of that quarter?

Instructions say one thing, form heading shows another, and application is leading me in a way I don't understand.

you can infer form lines 2 and 5 that is is cumulative from Jan 1.

What does the instructions say that is contradictory ?

the form is absurdly complex and I gave up trying to reduce my penalty.

I think Intuit has screwed up this form.  The line 1 instructions say to enter your adjusted gross income for "each" period. Fed instructions say "For each period (column), figure your total income minus your adjustments to income." That means to me how much adjusted gross income for each period, not accumulated.  I can enter the first three quarters but the program forces the fourth quarter which is my total it found somewhere else. I believe I should be able to enter each quarter.  An the column header shows date ranges suggesting the columns are cumulative.  (ie col a is 1/1/20-3/31/20, col b is 1/1/20-5/31 and so on)  I believe the column headers are wrong with date ranges and I should be able to enter each line 1 column myself (a-d).  I think this is a programing mistake by Intuit.  How the heck can I communicate that to them?
