I do not think I entered my health care information correctly when I efiled. How can I fix that after I efiled?

If you have not yet filed your tax return you can sign back into your account and go to Federal Taxes then Health Insurance. This will allow you to update the information. 

If you have already filed your tax return you need to first wait and see if your return is accepted or rejected. If rejected, you can go back and correct your health care entries, then re-submit your return.

If accepted, you need to wait until you receive your tax refund and then Amend your tax return using the Amendment Form 1040X.

Here is an FAQ with additional instructions on Amending your 2016 tax return. https://ttlc.intuit.com/replies/5114064
