How to prepare a ten columns work sheet using peach tree accounting software

I'm not familiar with the newest versions, but the older versions, both Windows and DOS, never did 10 column worksheets. Probably cause accountants never really use those things, or at least not the way books show you. (A 10-column columnar pad just has 10 blank columns that you can use for whatever serves your purpose.)

It's not necessary to have 10 columns - the software is going to do the statements for you. It does have a thing called (I believe) a "working trial balance" which has 3 sets of columns, double-spaced to allow working room, where you can scribble in adjusting entries. In real life we don't enter adjusting entries on worksheets in the software - that's done either manually or you can use Excel if you like. In other words, we work things out off to the side, and then we make normal journal entries for the adjustments once we have them worked out. In reality, they can be done in sets, re-run the trial balance to see where things stand, make more entries, etc.

If you're doing this for real life, you'll have to learn to stop taking textbooks so literally. If this is expected for homework, them, well, Peachtree just doesn't do it so I don't know.
