I had my tax return rejected from federal because form 8839 is requiring a child birth year even though the adoption is not final?

Has the child been born? Has the child been identified? If you have a birthdate, then enter it on Form 8839.

Qualified adoption expenses can't be claimed for the adoption credit until the year the adoption becomes final (or the effort fails). 

From How do I claim the Adoption Credit in 2020?

A domestic adoption is the adoption of a U.S. child (an eligible child who is a citizen or resident of the U.S. or its possessions before the adoption begins). Qualified adoption expenses paid before the year the adoption becomes final are permitted as a credit for the tax year following the year of payment (even if the adoption isn't finalized and even if an eligible child was never identified).
