Multiple 1099-R forms

I conducted a rollover of a 403(b) with one institution to a Roth IRA with a second institution.  I expected this to be a taxable event, and indicated in my transfer paperwork with the losing institution that the money was headed to a Roth IRA with the gaining institution.  

 

When I received the 1099-R from the losing institution in January, box 1 showed the distribution amount, and box 2a showed $0.00 (box 7 shows G, all others blank).  I contacted them, advised them that I thought the 1099-R they had provided was incorrect, and asked them to look into it. I was expecting to receive a new 1099-R with the full distribution amount in box 2a, and the "corrected" box checked.  

 

What I've actually now received is two additional 1099-Rs (a total of 3 now).  The first new form has the "corrected" box checked, but now shows $0.00 in both box 1 as well as box 2a.  The second new form I received shows the full distribution amount in both box 1 as well as box 2a (which is accurate as far as I'm aware), but this third form does not have the "corrected" box checked.   Both new forms also have code G in box 7, and all other fields blank.  

 

Did the financial institution handle the situation correctly?  Should the original mistake have been corrected by generating two additional 1099-R's?

 

Should I file all three of the 1099-R's I've received from this institution with the IRS?  Will the IRS know that all three of these 1099-R's are from the same, single transaction, given the manner in which they are filled out described above?  Or should I just file only the last 1099-R I received, which has the amounts correct in box 1 and box 2a, without a need for, or mention of, any corrected forms?

 

Thanks!
