Is distribution code G on a 1099-R correct, for a direct rollover from one retirement plan to another (no Roth IRA involved)? I am receiving error message. Please assist!

I received a 1099-R for a rollover. No Roth IRAs were involved. Turbotax is giving me an error message saying "You indicated that you converted a traditional IRA to a Roth IRA with Code G in Box 7. However, if this is true it should have Code 1, 2, or 7 instead.
If the money you took out isn’t from a traditional IRA, then the IRA box should not be checked.
If you need to make changes, select Back. If this matches exactly what’s on your form, we recommend you contact your provider to correct it." However, I believe Code G and the IRA box being checked are correct, since I indeed did a direct rollover from one retirement plan to another. Not sure if maybe there's an error in the TurboTax system, or if I'm misunderstanding something and there's indeed an error on my 1099-R... Thank you for any assistance with this!
