What if my distribution of has 2 digits 1M

[dmertz]

These are separate codes '1' and 'M.'  Mark the box on TurboTax's 1099-R form that is used to indicate that there is more than one code in box 7, allowing you to enter the second code.

Code M indicate that this Form 1099-R reports a qualified plan-loan offset distribution.  You have until the due date of your tax return, including extensions, to come up with the funds to complete a rollover of this distribution, allowing you to avoid the early-distribution penalty and to continue to defer the income.
