@qbteachmt @puravidapto @sjrcpa @BobKamman This just want an update, TP just e-filed f4868 via PTO (out of country extension from June 15 to October 15, 2021) and received an acceptance via e-file confirmation letter.

I must say that I got a wrong advice from one of the assistants at PTO informing me that the IRS does not process extension requests filed electronically after May 17, 2021 (f4868 -out of country extension from June 15 to October 15, 2021), I just have to print and mail the extension request out.  The PTO assistant was wrong.

Again, thanks for all your comments and time.
