My client became a resident taxpayer in 2019 (from B1/B2 to H1B). She had K-1 income from a partnership. The partnership didn’t know she became a resident taxpayer this year and still withhold tax from her and therefore generate form 8805. 

How can she claim the withholding payment back while she using 1040 tax form? What I know was Form 8805 can only be linked with 1040NR.
