The filing status (married filing jointly) on your income tax return does not affect how you file a gift tax return. You cannot file a joint gift tax return. Form 709 is filed by one person. If you want to split a gift, and the amount is over $30,000, you have to each file a gift tax return, but you file the two returns together. See lines 12 - 18 of Form 709, and "Lines 12–18. Split Gifts" in the IRS Instructions for Form 709. The first sentence under that heading says "Caution: A married couple may not file a
joint gift tax return." Also see "When the Consenting Spouse Must Also File a Gift Tax Return" in the instructions, and note that you do not meet the requirements for either of the exceptions in that section, since the total gift is over $30,000.
You cannot file a gift tax return with TurboTax. You might want to get help from a local tax professional for the gift tax returns.
