Is there a way to generate a year-to-date Profit and Loss (Schedule C) from Turbo Tax?

Like for 2020?  No.  You only fill out schedule C for the whole year in your tax return.  To get a Profit and Loss statement you need to use an accounting program like QuickBooks or Quicken.  And the IRS doesn't have the 2020 forms out yet.  You would have to print out a blank 2019 Sch C, cos out the 2019 and fill it out by hand with your current amounts.

Here is a blank Schedule C
