When I filed my tax return for 2016, I said I would contribute $6,500 to IRA for spouse, and got a larger refund on that basis.

But now on checking my investment accounts, I found I have already contributed $6,500 to Roth IRA for 2016.

Do I need to amend my tax return? Can I move the $6,500 from the Roth IRA to IRA for spouse, and then my tax return is still valid - but I think there is a penalty for taking distributions from Roth IRA before 5 years.
