QB, P/L, CoGS, & Income taxes question.... please help.

I'm using 2020 Quickbooks Premier desktop and TurboTax 2019 to do my business taxes. My QB Balance Sheet Report does not list the Beginning of Year and End of Year Inventory values under the GOGS header, but TurboTax and the IRS require those values when calculating my Gross Profit for the year.  My inventory numbers are correct.  When I pull the BOY and EOY Inv Valuation Summary amounts, then put those numbers into TurboTax with all of the other COGS values, my Gross Profit does not match my P/L sheet.  How is this supposed to be done for Tax purposes?  other info: I have been using QB since 2011, but it's the first time that I am doing my taxes myself.  I'm using Cash Basis accounting in QB and with the IRS.  My gross sales are under $50k per year for the last 10 years.
