My 1099R also has witholding. I want to allocate this to the beneficiary along with the tax liability for the income they received. However, Turbo Tax doesn't seem to be able to do that. I've entered the income in "other income" as described above. I've also entered the tax witholding and under the Turbo Tax forms, checked that this witholding is from a 1099 form. Per IRS, I should be able to issue a credit to the beneficiary in Box 13 of the K-1 for this "Backup Witholding" amount, but TurboTax doesn't include anywhere that I can specify this, so K-1 is not being filled out correctly and the backup witholding is being shown as a trust taxes paid amount.
