Why does your online say free for using w2g forms?

The Free online edition does not support entry of a Form W-2G for gambling winnings.

Go to the TurboTax website for the Free online edition.  Scroll down and click on Tax Forms.  The W-2G is not shown as being supported - https://turbotax.intuit.com/personal-taxes/online/free-edition.jsp#tax-forms

Use the TurboTax Free File program if you are eligible - https://freefile.intuit.com/
If you are eligible you can use the TurboTax Free File Program which is free to file both a federal and state tax return. The Free File Program edition is a full featured personal tax program and on a separate website from the TurboTax online editions.

To qualify for free 2019 federal and state tax returns with the Free File Program, you'll need to meet at least one of these requirements:

• A maximum 2019 adjusted gross income (AGI) of $36,000; or
• You qualify for the Earned Income Tax Credit (EITC); or
• You served as active duty military (including Reservists and National Guard) with a maximum 2019 AGI of $69,000 (you'll also need a military-issued W-2).

Where do you think it says that?  The Free Edition cannot be used for gambling income because gambling income requires the use of one of the extra schedules which are not supported by the Free Edition.

To enter the W-2G  or other documents For your Gambling winnings--Go to Federal>Wages & Income>Less Common Income>Gambling Winnings

You can enter your winnings, and then keep clicking through the interview to enter gambling losses.

Gambling winnings are taxable income.  Losses are an itemized deduction.  If you do not have enough itemized deductions to exceed your standard deduction, your losses will have no effect.

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.
