Utah State Tax residency date question

If my daughter is attending school at USU and she started Jan 1st 2021 and came home for 3 months during summer then went back again in the fall, would she be a part time resident or non-resident.  If she was a part time resident the tax question asked is what was your date of entry to Utah and what was the date of exit.  there are two times she entered as a part time resident and two times she exited in August and December.  What would be the correct way to fill out the form?  There is only an option on the tax form to fill out one time to enter the state and one time to enter.
