Do not attach explanations when filing the form. Wait until you receive a notice about penalty and interest from the IRS and after that provide your explanations. The IRS will decide if you meet the "reasonable cause" criteria and if you have to pay any penalties.

General instructions for the form are as follows:

6. You may round off cents to whole dollars on the main form and its schedules. Note that if you decide to round, you must round all amounts. If you must add two or more amounts to figure the amount you have to enter in the box, add them with cents and round off only the total.
