Retirement tax questions

SEP's are employer plans, not Traditional IRA's.    SEP contributions are entered in the schedule C section.  Nothing should be entered in the Traditional IRA contribution interview at all.

If you entered in the IRA contribution section then un-check the Traditional IRA box and [continue] to delete the improper contribution.
