I mailed in my taxes in March. The only income I received was from babysitting. I am a nanny 5 days a week in?

someone else's home. I never received any form from them. I used turbo tax, and claimed 8,000 from this couple I nanny for. I also earned other income from another family I nannied for, but I didnt receive a form from him either, but I just want to work on this 8,000 from the other family. I also claimed the earned income tax credit. I am a single mom of a toddler. I live with a roomate, no child support or other income. The eic was 2,955. Today the irs mailed me back my tax forms I mailed in, and a note for me to send proof of my income for the eic on a 1099 misc form. I picked up the 1099, but it looks as if my payers needed to fill it out, and send it to me by Jan 31st. They already mailed in there taxes. I also read that they will get penalized for not sending me the form. I know they also claimed somewhere in there taxes the 8,000 they paid me. What do I need to do? Is there a way to fill out the 1099 form, and only I send it in? Can this family I work for still send in the 1099 form, even though they already sent in there taxes? How much would this family I babysit for be penalized? Anyone know how much I would need to pay in? Would I be considered a late tax payer now and have to pay a penalty? Thank you so much!!!
