PUA Claim from 2020 finally paid retroactively in March 2021; NO 1099-G received and NOT included in 2020 filing

I applied for PUA benefits with State of Oregon in June 2020...and thanks to the inept computer systems etc, my claims were NOT processed and paid until early March 2021. Meanwhile I had already filed my 2020 taxes (using TurboTax) in February. So far I have NO 1099G paperwork from state although their system does show both federal and state taxes withheld from my checks issued in March 2021.

Do I need to file amended return? And must I secure paperwork (1099G) from State? I've asked State Dept of Employment for guidance, but they are clueless on what to do.
