I received my first stimulus check but didnt recieve a second one. I can't fill out the form for the rebate because I'm not getting a tax return since I didnt work last year. My fiance claimed myself

And our children last year and this year but it doesnt give him the option to fill out the rebate form. Any help would be greatly appreciated.

If your fiancé claimed you as a dependent, you are not eligible for the recovery rebate credit.  Even though you're not eligible, you will be able to keep the stimulus you did receive.  For your fiancé to fill out the Recovery Rebate Credit, he can click on Search, type "Stimulus", and click on "jump to stimulus".
