State tax filing

Maryland requires taxpayers to use the same method of calculating deductions on their state returns as they do on their federal returns - standard deduction or itemized deductions (see Item 3 on the screen shot below)

TurboTax will allow you to file a federal return (using standard deduction) and a state return (using itemized deductions). It requires a desk version (CD/Download) of the TurboTax program. You have to prepare two returns with the same income information but with different deduction options.
