Can I run a test for my 2019 taxes using all info I have now? See where I stand?

Trying to punch in some new numbers for 2019 and change my filing status to widower.  Site just keeps taking me back to my 2018 filing.  Useless!

Online is closed now to get ready for 2019.  It will open in December.  If you have the 2018 Desktop program installed on your computer you can use it to estimate 2019.  But it's probably not worth buying 2018 just for that now.

Use the TurboTax calculator TaxCaster to get an estimate of taxes owed or a tax refund - https://turbotax.intuit.com/tax-tools/calculators/taxcaster/
