@puravidapto @sjrcpa @BobKamman Thanks again all for your time.

Just had a chat with another PO assistant and she can confirm that f4868 can still be e-filed via PTO on or before June 15, 2021. 

Told her that I was advised earlier by another PTO assistant informing me that the system will still show as ready to be e-filed, but once it is attempted to be e-filed I will receive a transmission error.

I will try to e-file once I discuss this matter with client on the amount of payment.
