Can I still go back to my return to create the 1099-misc forms for my workers? I've already filed my return

As i entered my expenses, there was a link where I could create my 1099-Misc. forms for my contract labor workers. I clicked on it and let me begin filling out the forms. Unfortunately, it wouldn't let me continue claiming it was unavailable at that time. i tried going back a few times, but no luck. 

I ended up e-filling my return to the IRS, but i never finished filling out my 1099 forms. Will that affect my return?
