Confused 401k with Traditional IRA

Hello,

 

I just filed my taxes and realized I made an error. I confused my 401k as a traditional IRA. In other words, I claimed my 401k contribution as a Traditional IRA contribution.

 

I have a 401k and a ROTH IRA, but not a traditional IRA. I did correctly report my contributions to my Roth IRA.

 

Do I have to file an amendment right now or should I wait for the IRS to get back to me? I did not contribute more than the allotted amount (in my case $6,000). I do not think it impacted my return amount, but obviously want to do everything correctly! Thank you for your help!
