TurboTax does not support Form 709 and professional guidance is recommended.
Regardless, you can prepare and file one 709 for the two gifts (just list them separately in Schedule A).
You should not owe any gift tax unless you exceeded your lifetime exclusion ($11,700,000 in 2021) so, if you owe tax you most likely did not enter your basic credit amount on the form.

If the gift is of community property, then the gift is considered made one-half by each spouse.
