Hello, I just discovered that my IRA contributions for 2005 were $500 less than I reported on my return. I want to file an amendment and straighten things out. So my questions:
- Do I just include a check for the tax difference when I file the 1040x?
- How do I calculate any interest or penalities?
- Do I need to worry about this affecting my California State tax return? Thank you,
Dana
