100% false. Not tied to IP. Its tied to the Turbo Tax ID they force you to use before you can e-file. I know this as I have a block of IPs and 5 different computers I tried. This was only an issue recently as prior to 2023 TT filing you didn't have to use a TT account to file. The TT account was used to install and was enforced on 5 PCs to install. Now they force you to use TT account so they can keep a copy of your taxes on theirs servers and up-charge you for storage. Pretty soon you won;'t be able to do local install at all it will be $100 a pop to start online and 50$ for every additional form like Sched A, B,C and D like they currently do. Oh and another 50$ to state file which is currently included. Probably add another 50$ to state file (they did that one in NY and that state made them go back to free e-filing which is about the only positive thing NY has ever done for me.
