Retirement tax questions

What a mess I created for myself, and staring at staggering tax bill! But thanks for confirming my doubts.

 

Pl. clarify the following too.

- Besides all this screw up I also did another, which I hope is not a screw up

- In 2021, because of being 62 years old, and since the investments choices in my employer 401K really sucked, I rolled over all ALL of that 401K into an IRA that I already had (the same one that had mix of pre and post tax contributions)

- Both the 401K and the IRA are with the same institution

- They did the roll over directly without money changing to my hand etc

- They did send me 1099-R with code G also

- When I used to file 2021 return around march 2022, I chose to download tax forms electronically via Turbo Tax premium from my IRA/401K provider

- But I do NOT know if it covered 1099-R G code one or not

- And I filed the return already now

 

Now getting a doubt that I have to amend 2021 return to report this roll over. So I tried to use Tubotax 2021 to do prepare amendment with data from 1099-R. After entering all of it, Turbo Tax is telling me that it is NOT seeing any difference between what I already filed and the amendment I am now trying to file!

 

From this I am guessing,

a) Since the roll over involved 0 tax and 0 taxable funds, I do not need to  do anything extra than what TruboTax did for me when I originally filed?

b) OR I chose to download electronically, Turbo Tax took care of all this and hence I do not need to amend?

c) OR if the roll over involved 0 tax and 0 taxable funds, such roll over doesn't need to be reported at all?

d) OR I have to still  file amendment no matter what?

 

Pl. clarify the above.

And I did the same in 2020 (already filed) and 2022 (yet to file) also. So want to know if I have to do anything even for these two from the answers above.
