I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today.
Quite simply, there is no way to earn $25,000 per year and not have both your own early retirement befit, and your daughter's benefit decreased because of your additional income.
If you are under full retirement age for the entire year, social security will deduct $1 from your benefit payments for every $2 you earn above the annual limit. For 2015, that limit is $15,720.
In the year you reach full retirement age, social security will deduct $1 in benefits for every $3 you earn above a different limit. In 2015, the limit on your earnings is $41,880 but they only count earnings before the month you reach your full retirement age.
The social security benefits you receive are not included in that $15,720 limit.
Consequently, if you earn $25,000 next year, then your own benefits will be decreased by about $7,000 and your daughter's benefits will be decreased by the same amount.
Under the circumstances, it would make better sense for you to delay your social security benefit for another year or two. First because doing so will increase your ultimate benefit by about 6% for each year you wait between now and age 66, and second because what you are presently getting from social security for both you and your daughter amounts to about $27,000---but with the income penalty that will be applied, your net benefit after the penalty will be just about $13,000 for the both of you.
And if you do take the benefit in 2016 and do not tell social security that you will be earning that much so that they can decrease your awards, then you will be hit with an overpayment demand of about $14,000 as soon as you file your 2106 tax return in 2017.
