I made a mistake in using Turbotax where I added my self-employed consulting income twice. This resulted in greater taxes, but also an excess SEP IRA contribution. I am working on the 2015 1040X. Do I need to fill out a 5329 or 5330 for 2015? I am hoping I can do the 1040X with the corrected income and file with the correct SEP IRA contribution. I hope to then decrease my 2016 SEP IRA contribution. Does this sound correct?
