Retirement tax questions

I made the nondeductible (after tax) contribution to a Traditional IRA with the intention to then roll it to a Roth IRA as I have done in previous years.  However, I was told that I would not be able to do that because I now have other Traditional IRAs and the conversion to Roth would end up being taxable because I could not designate just this $7000 post-tax as the money I was converting.  (It would have to consider the balance of all my IRAs which are much larger and all pre-tax.).  So, Fidelity immediately returned the contribution and reported it on 1099R using the code "8" for return of contribution taxable.  I made the contribution in 2021 and had the return just a few days later.  I want to just remove that 1099R but I think I should somehow do it correctly now!  

 

So, I made a contribution with after tax dollars.

The contribution was returned with no gain.

I don't want to pay tax on the distribution.  

 

ANY thoughts would be appreciated.  THANK YOU for reviewing.
