I filed my taxes and then I received another w2 form by mail and I did an amendment adding the other w2 form by mail I have not received my check and I understand that it takes about 6-8 weeks and the question that I have is if there is a website where I can check information about the check?

Amended returns take over 8 weeks. You can not check the status online. You can call IRS after 8 weeks.
