When you enter numbers, use whole numbers and do not use commas or dollar signs. For example, $12,332 should be entered as 12332.
Use TAB or the Mouse to Navigate: When you enter numbers in the boxes, simply type the number in and then use the mouse/touchpad or TAB key to move to the next box. Do not use the ENTER key since that will probably cause the program to run the program. The ENTER key clicks whichever button is highlighted. Generally, that will be the CALCULATE button, but not always.
When the CALCULATE Button is Yellow: Whenever you change an entry somewhere in the program, the background color of the CALCULATE button will turn yellow. If you see the yellow background color on the CALCULATE button, you need to click it to calculate the results. You do not have to click it as soon as you see the yellow background, but you will need to click it eventually to see the correct results. In other words, the yellow background simply tells you that an entry has been changed and that you will eventually need to click CALCULATE to recalculate.
The Front Page is Not Automatically Calculating: Some of the pages are automatically calculating, which means that it automatically calculates the numbers on that page as you type them in and then leave that cell. The Income Page, Itemized Deductions Page, and Self-Employment Page, for example, do this.
IT IS VERY IMPORTANT TO REMEMBER THAT THE FRONT PAGE IS NOT AUTOMATICALLY CALCULATING, AND JUST BECAUSE YOU ENTER OR CHANGE NUMBERS ON OTHER PAGES, YOU WILL STILL NEED TO CLICK THE CALCULATE BUTTON ON THE FRONT PAGE TO ACTUALLY RUN THE FRONT PAGE NUMBERS. IT SHOULD NOT HARM ANYTHING TO CLICK THAT BUTTON EVEN IF YOU DO NOT NEED TO. THEREFORE, WHEN IN DOUBT, CLICK CALCULATE.
IF YOU DO NOT CLICK THE CALCULATE BUTTON ON THE FRONT PAGE, THE CORRECT RESULTS WILL NOT BE SHOWN.
Enter the Income Before Deductions: Since the amount of allowable Itemized Deductions depends on the amount of income a taxpayer has, you should enter the Income figures before you do the Itemized Deductions.
ESC Closes the Program: The ESC key will close the program.
