You did the right thing by posting the shareable link in the discussion forums. In most Coursera courses, the deadlines are not hard. You can continue even when the end date passes. At this point, you may receive your grade if your work has been graded by at least one learner. It looks like this is not a Degree course, so if your payment is not going to expire, you don't need to worry about it. This Help Article provides some more information: Assignment deadlines
It also provides a "Contact Us" option in case you are still uncertain about it.
