If you take the standard deduction this year but you have verified contributions of $300 or more as a single individual (or Head of Household or Married Filing Separate individual) then you get to enter $300 in 12b.
If you are Married Filing Joint and have verified contributions of at least $600 then you can enter $600 in 12b.
I keep entering 600. in this field. It accepts the amount, I save it, but when I come back to TurboTax I'm told there is an error in this field and it pops up as 300. highlighted in color. I am not able to make this correction. We're filing jointly as married couple and we're taking the Standard Deduction.

The solution recommended DOES NOT WORK when itemizing Arizona State. I deleted all my Charity Contributions and entered $600. Re-ran review and $300 was put back into the field. You can not put more than $600 on line 12b. I spoke with a live tech support person and was told that this is a problem that ha been flagged internally and there was NO EXPECTED RESOLUTION DATE. Frankly, I'm a bit disappointed as I have used TurboTax for years. Hoping tis gets resolved before the deadline.
