Does self-employment expense data entered into TurboTax the previous year appear in the current return, or must it be re-entered? My expenses are consistent year to year

I have a home office and am hoping to not have to re-enter the numbers each year.

No. Things like CCA and unused Business-use-of-home expenses will transfer, but other expenses like fuel, office supplies, etc. will need to be entered again.
