MD State Retirement Agency 1099-R -- box 17 pick-up contribution says "EP USED". However, TurboTax will only accept a $ value. What do I enter in TurboTax?

 When the pick-up amount reaches zero, “EP USED” will be printed in the pick-up block on your 1099-R. This usually occurs within a few years after the date of retirement so enter $0 in box 17, if there is an entry in Box 15, and box 16, otherwise leave it blank.
