Get your taxes done using TurboTax

Those are just the instructions for line 17, you would enter $150,000 if you are not married filing jointly, for married filing joint returns you would enter $300,000.  In your case, since you are single the entry for this line should be $150,000.  

You should not need to change any numbers on the Schedule 1-A because TurboTax calculates this line on the schedule based on your filing status.  If you have a different amount, you will need to go back through your My info section and check what your filing status is.
