Thank you so much
to be specific,
I paid tax when I received first notice exactly I paid May 24th and
Second notice (Cp14) was issued on June 3 and due date was June 24, but this notice was delivered on July 2nd.
Also my School office person told me, (my tax was for my scholarship and fellowship) IRS often update late so, if you paid exactly same amount, you can ignore.
I hope you and my school office are right.
Anyway thank you so much!
