When you log in, see if
there is a Taxes tab (link) up at the top. Clicking that should
take you to your Tax Timelines.
If it acts like it wants
you to start a new 2016 return, then you likely have multiple accounts and
signed into the wrong one.
Use the tool below to look
for multiple accounts (User ID's). Run it on each email address you have.

If still no luck, then you can run that tool
again, but this time choose the tiny link that says "I don't know my email
address or user ID", and it will then try to look you up by SSN and other
parameters.
