I moved from Virginia to Washington DC last year and my wages were taxed as a Virginia resident and a DC resident. Do I need to fill out state tax forms for DC and VA?

I lived in VA for 9 months in 2021 and moved to Washington DC where I spent the remaining 3 months. After I moved, I was taxed as a DC resident. Do I need to file returns for both states? Do I need to divide up my wages to wages earned in VA and wages earned in DC?
