Can't add Googgle account on both iPhone's Mail app and Mac's Internet Account

Hi fam, I really need some help here! 

I recently changed my GG account password and the account still works fine on the Chrome browser on my Mac and the other GG apps on my phone. After several days of changing the password, my phone kept asking me to re-enter the password in the settings app within the mail section. However, for some reason, the re-enter command doesn't work and I can't re-enter the new password. So, after so many trials, I decided to delete it and re-submit my account. But, I CAN'T!!! 

I did try to add other accounts (iCloud, Microsoft Exchange, and Outlook.com) and it worked, I also tried to use "Other" to add my GG account, but it STILL DIDN'T WORK...

The pictures below was when I researched and tried to use the "Other" option and on Apple Support it showed me the IMAP info to fill in but I still couldn't add my account... 

I also lost most of my contacts on the phone app... I am so LOST and so very CONFUSED...

Today, I opened my laptop and tried to see if I could try to add my GG account on the Internet Accounts. But, I CAN'T!! It didn't open Safari or Chrome.. I don't know what went wrong... Please help!!!
