A. You have several options -
Option A. Recharacterization
If you qualify for Traditional IRA, recharacterization is a good option, because you don’t lose earnings and the money still goes toward your retirement, and you will get a tax deduction for your contribution.
Withdraw Excess Money
If you don't qualify for Traditional IRA, you can withdraw the extra contribution and any earnings before tax deadline without penalty. The earnings will be reported as income.
Apply Excess to Next Year's Roth IRA
Doing this on a future tax return may not let you avoid the 6% tax this year, but at least you will stop paying once you apply the excess.
