Here is a link to Publication 537, Installment Sales.  It discusses how, what property is eligible, where/how to report.

Your question is very brief, I'm assuming you sold a business.  If so, you have to allocate the sales price amongst the various assets sold and follow the rules for each type of asset.

Also, you don't mention if there is stated interest or not.  If there is no stated interest, or the interest is less than FMV, you have to consider imputed interest as well.  That is discussed in Pub 537 also.

The general rule for installment sales is sales price, less basis=gain or loss.  If loss, than no installment sale for tax purposes.  If there is a gain, you report the portion of sales proceeds received, less the pro rata share of basis=pro rata share of gain to be reported in the year.  Over the course of the installment sale, the portion of basis and gain is reported based upon the ration of the sales proceeds received.  This is for qualifying property.
