JOB Background check

So I accepted an offer for a bank as an IB summer analyst and tripping about the background check. I have verified my most recent banking internship with pay stubs and offer letter, my last two jobs as a lifeguard and my college education. BUT, I have on my resume some bs high internship I did for two weeks. They asked for verification, but it was very informal so I had no offer letter or pay stubs. I reached out to my previous hiring manager and he still works there and said he would verify for me. The thing is, on my resume it says May 2022 - July 2022 which I realize is an error and should be May 2022- Late May/Early June (I don’t remember) So I extended the period over a month. My hiring manager told me he had a quick 90 second call with  HR and he verified I was there but i’m worried HR noticed a discrepancy in the time frame of my resume and maybe what he said. Am I fucked?
