Retirement tax questions

I went back into the program and changed my answer to the annuity question is line 2 always the  taxable amount you used in the past? (or something to that effect).  I said no and then it allowed me to input the taxable amount  Then I went to forms and did a revised 1099 form with an explanation.  Hope this was the right way to do it, but for those of you looking for the same answer, this is how I did it because no one answered.
