Cannot get status of deceased mother's 2022 Virginia state tax return

I prepared my deceased mother's 2022 tax returns (Fed and Virginia) using TurboTax and e-filed both on 2/23/2023.   Both returns were accepted.  Fed paid refund via direct deposit 8 days later; Virginia state return shows no new status.  When I called the Virginia Department of Taxation for a status update, they told me they could not talk to me about my deceased mother's tax return status because I was not on the account.  They told me I needed to submit a Form 1310 (I did -- it was included in the e-file).  I asked them what I needed to do so that they would talk to me about status, and they kept referring me to Form 1310.  So, I faxed a physically signed copy of Form 1310 along with my mother's death certificate.  They told me it would take 6 weeks to process.  All this just so (I assume) someone can provide me with a status update on the refund.  I'm feeling that the Form 1310 that TurboTax e-filed either didn't get to the Virginia Department of Taxation or was somehow deficient in whatever Virginia needs.  Any idea why Virginia is holding up the refund while the IRS processed without delay?  How can I get out of this endless loop of guessing what Virginia needs from me when they say they can't discuss with me?
