I'm not specifically familiar with VA rules. That said, I'm not finding any reference to an add back of previously deducted 529 contributions in the VA form 760 instructions (https://www.tax.virginia.gov/sites/default/files/vatax-pdf/2022-760-instructions.pdf)
Although recapture is common in many states, there's usually a line, right on the tax form, for it.
I do have the VA software and don't see a place to make that adjustment.
