How to remove and add back google account for android 4.4.4

[AC Question]

I'm using Alcatel one touch flash plus. When I go to settings, I scrolled to accounts , it shows all the accounts but no remove account only add new account.

I have a problem with my google play store is: error 491.
I've tried all the recommended solutions but to no avail...what i have yet to try is remove Google account and to add it back coz couldn't find the remove account icon. Tried tapping it, it just opened up with more details info

Anyone ....pls help!

That is precisely what you need to do, remove the Google account, reboot the device and add it
