Deductions & credits

The definition of improvement v. repair is more pertinent regarding whether or not to capitalize the cost or expense it. If it is capitalized, it must be depreciated whereas an expense can be claimed in full. TurboTax will walk you through recording any expenses or improvements.

See: What is rental depreciation and how does it differ from an expense?

Regarding personal use days, the days you stayed on the property to complete the renovation are not personal use days.

See 2020 Publication 527, page 18, column 2 and page 5:
