@dmertz, I thank you for your reply and sharing. Your assessment matches mine that all three 1099-Rs should have been G and only G in the box which means the new record keeper is correct.
In the first case (7G) they left box 2 at zero which is clearly incorrect and I reported it as taxable and paid the taxes on it. The IRS questioned this after I filed, agreed with me that the box 2 amount should have been = 1 box 1 and later I got the first corrected 1099R. This one contained other discrepancies which resulted in a second corrected 1099R.
In the second case, I hope the IRS did the same with the B and kept the G. In any event, the correct tax was paid.
