Retirement tax questions

AH, soooooo!!  I'm starting to see the light.

The problem I was having was on the page where it asks you to enter the Annuity Information.  There are four boxes:

Annuity Start Date

Plan Cost

Number of Months Payments were received in 2019

Tax-Free Amount Previously RecoveredThis is the box I was struggling with

 

The above-referenced page with the 4 boxes does/doesn't come up, depending upon the answer to the question provided on the page before, which is:  "Was the amount shown in the taxable annuity box the taxable amount?"  There are two possible answers:

1. Yes, the taxable annuity amount was used as the taxable amount,

2. No, a different amount was taxable

 

Both the question and the first answer are confusing to me.  There is a Taxable Amount box (2a) on the 1099, but not a taxable annuity box.  What did make sense to me was that the taxable amount (2a) is different from the Gross distribution amount (Box 1), so I chose the second option.  But that's the option that caused the four questions to appear (and my headache).    So, in plain English  🙂  LOL, what are they really saying when they ask, "Was the amount shown in the taxable annuity box the taxable amount?"  What is the taxable annuity box?
