After an hour wasted on the phone and 2 dropped calls. This is the only solution that worked! This needs to be pinned to the top! TT representatives had no idea that this glitch exists. I tried everything. Different PCs, browsers, etc. Nothing worked! This was the only solution! Thank you!
Solution: Click "Federal Review", then do NOT try to fix any errors. Just click next or continue. The live calculator magically shows up.
