It's rarely beneficial to file as married, separate, but it never hurts to run the numbers. If you claimed dependents, then yes, TurboTax asks several questions about the children to determine if they qualify as dependents. This is especially true when you have elected married, separate returns. Instead of changing your entries in TurboTax, I suggest using our TaxCaster to run your simulations. https://turbotax.intuit.com/tax-tools/calculators/taxcaster/
