1099R Rollover with Distribution Codes box not checked?

In  2017 I rolled over a 403B from one account into another 403B account. The  1099-R sent to me by the company I rolled over from had correctly labeled the rollover Distribution Code as "G,"  but the box next to Item 7, Distribution Codes,/IRA/SEP/SIMPLE, isn't checked. The company says that is right, as I didn't take possession. Turbotax doesn't like this and seemingly expects the box to be checked. How do I resolve?
