I gave Credit Karma Tax a try this year. I mostly liked it, but did find one serious deficiency compared to others I've used. It did not handle the deduction for state income tax nearly as well.
The IRS allows deducting either the actual sales taxes you have paid, or you can use a standard amount based on your AGI and your state and local tax rates.
Most other software I've used knows about this. If you enter your actual amount (or 0 if you do not know the actual amount) they compare to the standard amount and go with which is higher.
CKT just goes with what you enter. If you ask for help on that item it doesn't even mention the existence of a standard amount. It just says fill in the amount you get from adding your receipts.

At the very least the help for that item should mention the option for deducting a standard amount, and should link to the IRS' online calculator for this: https://www.irs.gov/individuals/sales-tax-deduction-calculat...
