@AkinaLO This problem occurred for me too. Does the calculation error indicate a security breach? Was Intuit.com or TurboTax Online forged?
While I believe that I filed an extension by entering the data via Intuit with Easy Extension, I was never asked to sign in to my account. I filled in the data correctly but when I view the printable 4868 copy, the math is incorrect.
Either Intuit doesn't understand how to program a form so that dollar amounts less than zero are listed as "0", they didn't bother to program it display correctly on the PDF version, or someone fooled a bunch of us into entering our most valuable PII into a forged website made to imitate Intuit's. I'm happy to share a screen clip of the 4868 PDF as it looks to me on a Mac (without my personal info of course). Perhaps this link will work: https://imgur.com/a/us4yMcp
