Application: Date of Enrollment Help

I’m currently filling out transfer applications and I’m having a little trouble with the section for schools attended. I returned to college Fall 2020 after time off and began attending the school I previously attended a couple years ago. I have nearly finished all the ge requirements (1 class left) and prereqs. During my previous time in school I had only completed 2 or 3 classes.

Now I’m filling out the applications and wanted advice for what my start date is. Should I put the year I returned (2020), the year I initially enrolled, and/or see if I can submit the same school twice?

Has anyone else ran into this issue?
