You can leave Box 9a blank. This only applies if you received a distribution that only partly belongs to you; that's when you would enter a %.
Here's more info on Box 9a.
If this doesn't resolve the error, delete the 1099-R and re-enter it manually. If you're using TurboTax Online, you should close the program, clear your Cache and Cookies and re-try.
