Samsung Tab 4 will not let me sign in to one of my Google accounts

[AC Question]

I bought a new Samsung Tab 4, while setting it up, one of my Google accounts signed in just fine but the other will not. During the sign in process I get sent to browser sign in and prompted for the two step sign in. I input the code sent to my cell and can login with the browser but it never translates to the actual Google account on the tablet.

I've tried everything I found on Google Support and even factory resetting the tablet but nothing is working.

Any ideas what is causing this? Thanks
