What to put for tax liability for state return

[shbqqa]

For last year's state taxes, I originally put that I was supposed to get a $50 refund, but later Maryland reviewed my returns and said I wasn't getting any refund (so tax liability ended up being $0 for the year). So, when completing this year's taxes, in the part where I need to include tax liability from last year's taxes for my Maryland state return, would I put $0 or $50?

Your tax liability is neither $0 or $50. Your tax liability is the total amount of tax on your income minus any non-refundable credits.

• On your 2020 state income tax return, look for the line that has the tax liability or total tax amount. 
• For example, on the state of IL Form IL-1040, the tax liability is on Line 23, Total Tax.
