Can I return to my federal form to make a correction? interest figure doubled, needs to be corrected.

If you have not already filed your return, then, yes, you can make a correction.  See the steps below to be brought back to the interest income section:

If you have already filed your tax return, then your only option will be to wait and see if your return is accepted by the IRS.  

• If the return ends up being rejected by the IRS, then you will have an opportunity to make the corrections you want to your tax return and resubmit it.
• If your return is accepted by the IRS, then you must file an amended return (Form 1040X)to correct the error.  Below is a link with more information on filing an amended return.  And note that amended returns must be mailed as they cannot be e-filed.
