I attempted to log into my Taxact account and was unable to get past the verification stage. I was prior, able to receive an email with an OTP to log in. I tried to recover my account, but you must put in your address on file, (U.K) and the system will only allow a U.S. address. I called their support and the upshot is, unless you have a mobile phone that supports verification codes then you are totally and forever locked from your account. I did argue that you've already verified me on the phone, or we'd not be having this conversation! The reply was you MUST have access to that number, or set up a whole NEW account!! Of course i'd never get past the verification stage to open a new account, as my number is not (in their view) able to accept verification codes.
There was discussion about Taxact and the all new ability to use a credit card with a whitlisting that actually worked perfectly. Also talk of apps that you may text on. Well in order to be able to receive a verification code, you have to upgrade to a paid service subscription.
So if you do use TaxAct, perhaps try and sign in now and make sure you've retained access.
I did try another prep software and my Voip phone did receive an OPT with no problem. The UI of that software is nothing like the quality of TaxAct though.
