return of excess contribution:
before tax filing date including extension: positive earnings allocable to the excess are included in income on 1040 Line 4b for the year of the contribution. negative earnings are ignored; in any case, for purposes of basis, consider the original contribution amount as returned.
["Include the earnings in income for the year in which you made the contributions, not the year in
which you withdraw them."]
You must have a) filed by tax day, or b) requested an extension of time to file by tax day to take advantage of the Oct 15 deadline.
Consult your custodian to obtain the correct removal form "excess plus earnings".
