This seems to be the most likely scenario -- not necessary to print Form VA-8453F within 3 days of acceptance. Mentioned in the link @Anonymous_ provided https://www.tax.virginia.gov/sites/default/files/inline-files/va8453f-2022.pdf states the form is to be signed but not mailed. The message in TurboTax Virginia state filing is likely a reminder to sign and date the form, which was done for the Federal return. Thank you!
