In the regular Turbo Tax Free Edition, information that you can enter is limited now. Why do I have to upgrade from the Free Edition?

To go back to a lower version or the Free Edition you can try to clear and start over https://ttlc.intuit.com/community/using-turbotax/help/how-do-i-clear-and-start-over-in-turbotax-online/00/26444
OR There is also The Turbo Tax Free File program which is free for federal and state. And has more forms than the Federal Free Edition, like Schedules A, B, C , D, E, F, EIC, H, K-1, SE, etc.
To qualify for the Free File website you just need to meet one of these 3 things
AGI $36,000 or less
Active duty military with AGI of $69,000 or less
OR qualify for EIC (earned income credit.)
In order to use the Free File program, you have to start it at a special website. Try signing in at the top right

The tax forms for 2019 include a Form 1040 and three possible extra “Schedules”:

https://www.irs.gov/pub/irs-pdf/f1040s2.pdf
https://www.irs.gov/pub/irs-pdf/f1040s3.pdf
If you need any of the schedules you cannot use the Free Edition.
WHY DO I HAVE TO PAY? I WANT THE FREE EDITION
The information that you can enter in Free Edition is pretty limited now. Thanks to the new tax laws that began for 2018 returns, there are no more simple Form 1040EZ or 1040A's. Everything goes on a Form 1040 that has three extra "schedules" with it, and if you need any of those schedules, you are not able to use the Free Edition. Using the standard deduction instead of itemizing does NOT mean you will not need any of those schedules.
