In previous years I was able to report 1099-B, stock sales with the free editionm based on my income. But for my 2019 filing wants me to upgrade. is this right?

TurboTax has 2 free products.

The regular Free Edition is for very simple returns and not everyone can use it.  Certain forms are not available in Free Edition and require an upgrade , such as one of Schedules 1-3, itemized deductions, education credits, student loan interest, retirement savers credit, etc.    It cannot prepare a Schedule D to report a 1099-B, which in a paid online edition would require an upgrade to Premier.

The other free product (TurboTax IRS Free File Program) is fully-featured and can prepare all the usual forms and schedules.  For example, in addition to Schedules 1-3 it can prepare Schedule C, D, E, F, etc., and enter K-1. But one has to meet one of the qualifications to use.  See below:

To qualify for free 2019 federal and state tax returns through the IRS Free File Program delivered by TurboTax, you just need to meet one of these requirements:

• Your 2019 AGI is $36,000 or less (for Married Filing Jointly returns, combined AGI of both spouses cannot be over that limit),  or
• You qualify for the Earned Income Tax Credit (EITC); or
• In 2019, you served as active duty military (including Reservists and National Guard) with a maximum AGI of $69,000, and you have a military-issued W-2.

If you qualify for that program and want to use it, see these 2 FAQs:
