i want to revert the pending accountant copy created no need to send it to the accountant
That is a Desktop version task but you tagged your question as using QBSE (online self-employed) which has no accountant's copy
To remove restrictions on your DESKTOP company file imposed when you created an Accountant's Copy
That should get you back working with no closed period date. You can physically delete the Accountant's Copy you created or just ignore it.
