Box 11 is blank on the 1099-R for an inherited IRA

[debifox]

The IRA was inherited from my mother therefore I can't make any contributions to it. Box 11 requires the date of the first year of designated Roth contributions but, the 1099-R Box 11 is blank and flagged that I must enter a date.

Form 1099-R Box 11 reports the year in which the designated Roth account was first established by the recipient. This is the first year of the 5-tax-year period for Roth IRA calculations. If you don't know this date, you may need to contact the IRA administrator for further help.

Enter any year more than five years ago.
