On the 1099R the taxable income is undetermined. If I file return with incomplete 1099 will IRS correct my return?

I completed the Worksheet A and B in pub 721, but am concerned that the information I am putting in the worksheet for contributions is not correct.

There's no really no way to tell if the IRS will correct your return or not -- assuming it's wrong.

Just double-check your math on the worksheet.  If you think it's right after review, it probably is, and you shouldn't have anything to be concerned about.
