Can I file married filing jointly and married filing single to see which way will get me the best refund?

Married Filing Joint is usually the better filing status.  To get a quick idea you can use TurboTax's TaxCaster, enter your information as Married Filing Joint, then go back through to enter each of your information as Married Filing Separate.

If you decide to file as Married Filing Separate with the Online version, you will need to file 2 separate returns and create a separate account for your spouse.

There is no Married Filing Single...it's Married Filing Separately.

The easiest way to test scenarios is to use TT desktop, but you need a computer to do that. Hwever, Joint is almost always better.
