Question

1099R data apparently not transferring correctly to Form 1040.

Line 5a on Form 1040 which shows the total amount of all pensions and annuities is correct.

Line 5b on Form 1040 which shows the taxable amount of all pensions and annuities appears to be incorrect. The amount appears understated.

The taxable amounts are based on the amounts shown in Box 2a of each 1099R which has an entry in Box 2a.

One 1099R shows taxable amount not determined in Box 2a. For this 1099R the taxable amount is figured based on the Simplified Method. As it has been for the past many years.

When I manually add up the taxable amounts and compare that sum to the amount transferred to Form 1040 Line 5b there is a difference of $1609.

The amount appearing in Line 5b appears to be underreported by $1609. I have been unable to account for this discrepancy.

I rechecked the 2024 version of Turbo Tax Deluxe and Form 1040 Line 5a and 5b are accurate. The taxable amount on Line 5b matches the amount I manually calculated.

I would greatly appreciate any help in explaining what may be causing this difference and how to resolve it. Thank you.

    Is my face red! Sorry everyone. After doing more digging I determined that the supposed error is not an error at all.  The difference I was seeing was due to how, on one of the 1099Rs, the Simplified  Method calculates Line 14, Taxable Pension for the year. That amount is slightly smaller than the amount appearing in Box 2a of the 1099R. I apologize for any confusion I may have  caused.
