In the regular Turbo Tax Free Edition, information that you can enter is limited now. Under the new tax laws, there are no more simple Form 1040EZ or 1040A's. Everything goes on a little Form 1040 that has six extra "schedules" with it, and if you need any of those schedules, you are not able to use the Free Edition.

Did you file yet? It is too late to file from online unless you need to fix a rejected return.
Online is closed now so you can not start a new 2018 return. Oct 15, 2019 was the last day to efile. You need to buy the 2018 Desktop Download to do 2018 now. You can buy 2018 Desktop download on the prior year products page here,

You now have to print and mail 2018. Be sure to attach copies of your W2s and any 1099s that have withholding on them. You have to mail federal and state in separate envelopes because they go to different places. Get a tracking number from the post office when you mail them for proof of filing.
