Hello. I filed my 2023-tax-reund using the desktop program. However, I'm unable to find a copy anywhere in my computer or online. How can I find it?

My Federal return has not arrived yet even though the IRS website says they sent it on APr1st. So, this is why I need to provide the details on what I entered in my e-file return. Also, I'm wondering if there is an email address to which I can request for this information (copy of my e-filed tax-refund file)
