Sole Proprietorship to an LLC

[Commander2000]

I changed my sole proprietorship to a single member LLC mid year 2020. They are same business, just  a structure change.  Do I file 2 schedule C's or combine the activity in to one Schedule C?

Yes, you should combine the business activities and file all income and expense items on one Schedule C.

As a single member LLC it is treated the same way as the prior Sch C ... other than adding the LLC's EIN to the Sch C nothing else changed on the tax return.
