Please help with check engine light
So yesterday I changed the oil on my 2017 honda accord sport my car takes 4.4 quartz i bought a 5 quart gallon i filled it up until the gallon marked 1Q idk if i over filled it or didn't put enough but i then checked the dipstick and it was marking that the oil was above the maximum dot i went to do something and after 15 minutes before I drove the car I checked it again this time it was marking barely above the minimum dot. On my way home i noticed the car weird i would step on the gas and it would feel stuck then like a jump and then accelerate fine. When I got home I took a 3 hour nap as I work graveyard then before driving the car again I checked the oil & marked in-between the minimum and maximum dot. I left it like that then later that night on my way to work the check engine light came on and now I'm worried what if I put too much oil or just not enough. After my shift I had a co worker check the oil level it was still the same in-between minimum & maximum he said to to it off and hopefully that fixes the check engine light issue but I was not comfortable about the idea so I took the car to Autozone to get it scanned and it's coming back to my catalytic converter being bad. Now idk if it really is that or not just seems weird that after the oil change the car felt weird then the light came on if anyone has some idea or know anything of what it can actually be I would really ask it. Thanks
