I didn't receive EFIN from IRS yet, and I purchased five returns, so what do I have to do.
In the meantime, you can prepare paper returns so long as you have a valid PTIN.
Once you receive your EFIN, follow the steps in this article to register the number with Intuit so that you can e-file: https://accountants.intuit.com/support/en-us/help-article/account-management/register-efin-proconnec...
You don't have to wait for the EFIN letter to arrive. Your printout of the EFIN Application Summary from your IRS account is good enough.
Unless, of course, those first five clients tell you that they don't like e-filing and want to go down to the Post Office and mail a paper return. That's assuming that you are going to prepare more than 10 returns. If not, you can paper file 10 returns without an EFIN and without getting in hot water with the IRS.
