If the tax refund has been handled and entered the treasury processing link, it should wait until the treasury processing is over before making corrections; If you have not applied for tax refund or have applied for tax refund, but the tax refund process is still accepted and reviewed by the tax authorities, you can cancel the tax refund application first and then correct the declaration.
If it is true that the withholding agent has made a wrong declaration, it will make a correction declaration and then make an annual final settlement.
