Question about IRA and filing an amendment

I filed my return in April as I was under the impression that I had all the paperwork I needed, wasn't planning on contributing any more to my Roth IRA, and knew the total amount I'd contributed.

 

On July 27th I got the final form 5498 from my broker and I realized that I'd made a mistake in how I filed. The overall amounts were the same but I'd accidentally lumped a Roth IRA conversion and the total Roth IRA contributions into one instead of classifying them separately which is what I was supposed to do.

 

I did the amendment in TurboTax and when I was done it said something to the effect of "We don't detect any differences between your original return and amended return Are you sure you need to amend?"

 

I tried calling the IRS to find out if I should file an amended return even though the dollar amounts are identical with the only difference being the way it was entered but I have not been able to get through even though. I've tried calling several times but always get the message that they are too busy and to try again later. So I thought I'd ask here and see what the recommendation is in this situation.

 

Thank you for the help and advice!
