Ohio Food Stamp elegibility?

I was laid off in October and am receiving $302 a week on my unemployment. My husband was laid off over 3 years ago from a union painting job and his unemployment ran out two years ago, so he brings in no money at all. We own our own home, mortgage payment about $445 plus the regular utility bills. No credit card or car debt (thank God). Using a gov’t calculator tool it seems we may qualify for food stamps but there’s just one question. I have a SEP retirement fund set up at the place I was laid off from…….no contributions from my company. I have invested about $21,000 over the course of time, but with the bad economy, the account is worth less than $13,000 now. Also there is the penalty for early withdrawal (I’m 57) which would be a double hit. The food stamp guidelines say that a person of my age can have no more than $2000 in saving. Does that include my retirement plan?
