According to my understanding, you declare the value-added tax of the tax period before copying the tax, which makes it impossible to clear the card.

First of all, you should first check whether the period of successful tax declaration is consistent with the period of tax copying, and confirm whether the period of tax declaration is the same period, so as not to mislead the corresponding work.

If it is confirmed that the declaration period is consistent with the tax copying period, then you should cancel the declaration first, and then follow the requirements of the tax copying process, first perform the tax copying and then operate other processes of the declaration work, and finally clear the card.

If the tax paid cannot be revoked, you should contact the competent tax bureau in time to consult the solution.

It should be settled as soon as possible in this tax period to avoid other troubles.
