We are filing an extension - we used the TaxCaster tool to estimate our taxes owed. The turbo tax extension page that says "Let's Estimate your 2016 taxes" has a blank for "total taxes owed". After completing all the steps in the tax caster, it did not have a line for taxes owed. Instead, it has a line for "regular taxes" and another line for "tax credits". Should we subtract the tax credits from the regular taxes line before entering it as "total taxes owed"?
Thank you...this is the first time we've ever filed an extension & we don't want to make a mistake.
