No, you are too late to request an extension unless you are out of the country. Now your tax return is just late. If you are getting a refund there is no penalty for filing after the deadline. If you owe tax due, your penalty and interest are starting to add up already.
You are posting from Live Deluxe, which means you are paying for Live help to answer the question about why your return seems "off".
You can arrange for the Live help you are paying the extra fee for with your questions from 8a.m. to 5 p.m. Pacific time Monday - Friday.
