yellow oil light comes on a day after oil change

i would say you failed to fill it and need to add a quart.

yes I was going to add another quart but why is the oil level below the minimum? it almost looks like there isn't any oil in it but I know there is... is there something I need to reset?

it is low because you didn't put enough in when you changed it and now the light and dipstick are telling you you need to add a quart.

I would have to agree with the previous responses. You may not have filled the crankcase to spec. Try resetting the oil life and see what happens. If it comes back on then you'll know you need to top off the oil. Careful not to add too much.

chances that resetting the computer will increase the oil level on the dipstick are somewhere between slim and none.

Did you ever find out what the issue was?

I had the same problem, added 1qt, the light was still on, I had to wait 45 min with the car shutdown for the sensor to re-calibrate. All good now, this happened after 5,000 miles/6month from oil change.

ive had two oil leeks thay have been fix but can you tell me were on the dip stick were abouts the oil shoud be cos i see no oil burning and no oil leck my oil light keeps coming on
