Investors & landlords

Thank you. Doing the same for my wife (we file jointly, i am primary tax payee) and she has ~28k in her traditional IRA out of which 12 k is non-deductible and the remainder was rolled over from a prior employer's 403b plan. That would mean we owe >$1000 in taxes which I should probably pay in advance. How can I make that estimated advance tax payment in her name?
