Only want to calculate, print, & pay for Fedl tax return. Will do state manually. How can I do only Fed'l?

Just do not start a state tax return after you have completed the federal return.  Click on Review and then click on File.

If you have started a state return see this TurboTax support FAQ for deleting the state tax return - https://ttlc.intuit.com/community/using-turbotax/help/how-do-i-delete-my-state-return-in-turbotax-on...
