Tax Due on RMD

I am 75 and as of May 2021 I was still working full time with a company 401K. At the same time I had another retirement account which I had been regularly getting an RMD and calculating that for tax purposes. 

In January of 2021 I  took out my RMD (for 2021) from the retirement account (including a 10% withholding)

I retired in June of 2021and closed out the 401K account and transferred the total balance over into the original retirement account, this doubled the total Retirement accounts balance.

I received a 1099-R with box 7 as G (Total Rollover)

Before the 401K closed out I took an amount from the account to cover any RMD????? (-10%)

Am I due any more required RMD for 2021?  As the amount I took from the Retirement account in Jan was for the balance as of Dec 2020.
