Summer course between 1st and 2nd year transcript?

If I did 5 courses per semester my first year, and did a second year course in summer, does that summer course go into my first year transcript or my second year transcript?

I will also be taking 5 courses per semester in 2nd year too, although i might drop one elective on 2nd year fall term. Will this affect my transcript?

I don’t know if this is relevant but the second year course i took is required in my program to take before 3rd year.
