Rollover from 403(b) to Traditional IRA in year 2020, but didn't file 1099-R

Hi, I rolled over from employer's 403(b) to Traditional IRA in Year 2020 (5 years ago!!!). The 2020 Form 5498 reflected the amount. However, I just realized it today that I didn't fill in 1099-R back then. What should I do? Thank you for reading.
