I am not sure if the online account will show Form 709 for your dad. It will not be in your IRS account--if it is in an online account with the IRS it will be in your father's online account. Also not sure how often those online accounts update, and it seems all of this is fairly recent--during April 2024. Your dad can call if you are worried whether the IRS received the form.
