This can happen when VA has accepted the return, but not completed the processing of it. Accepted means that have accepted the file from TurboTax, but they still need to process it. Give it a few days and then try to see if you can track your refund.
If you are unable to track your refund you can call the VA department of revenue and speak to a tax representative. They will be able to answer your questions and let you know what they are showing in their system.
