The Notice does not make exception for 1099R reporting for distributions, but did you even make a distribution? If you just moved funds from the brokerage account to what you describe as a 401k bank account as opposed to a personal bank account, then the funds never left the plan. In that case there was no distribution and no need for a 1099R or reporting a distribution and rollover on your return. Also no impact on your 5500 EZ.
However, all this does raise a question regarding distributions including RMDs for other years. An RMD must be distributed to an account that is outside the 401k plan.
