Retirement tax questions

Distribution Code G would only apply if this were a direct rollover - Fidelity moved the funds from a one retirement account registered to you directly to another retirement account registered to you.

If Fidelity distributed the funds directly to you and you moved them into another IRA account (even if held  by Fidelity) then Distribution Code 7 was correct. 

The 1099-R interview for the 1099-R, asks "What did you do with these funds?" If you answer that "you moved the funds to another retirement account", you won't be taxed on the rollover.
