Peachtree, inputting income through general journal and having it show up on the general ledger?

I have been trying to get the income my company receives, inputted into peachtree accounting. We keep our income records under Microsoft Access, and we are trying to input the amounts so it shows up on our general ledger. We have already been posting expenses onto peachtree so updating the chart of accounts for income is tricky. i was told to use the Journal entries… which i have. The updated info shows up on the Income statement, but not on the general ledger… how come?
