I used Turbo Tax Business to file LLC returns. I want to file an amendment now. How do I know which IRS center processed the original return?

What form did you file ?   1065?  1120? 1120S?

If you filed a 1065, then select e-filed when you are preparing your amended return (see screenshot).

Subsequently, enter Forms Mode and click Filing Instr (Instructions for Filing) which will show the service center to mail your return.
