I have several fields on a form:
Price = [user enters and it is added to a table]
Qty = 19 (user enters)
each price = $.0489 (user enters)

total price:  $9.291 (calculation on the form based on [qty]*[each price]

the user can enter a qty and a each price which would give them a total price.  How do I get the total price to populate in the Price field?  The price is populated with default values or the user can overwrite the default value)

As long as you keep the UnitPrice and the quantity, there is no need to keep the ExtendedPrice.  It is far better practice to calculate it in the query.  Doing the calculation in the query will also automatically populate the ExtendedPrice field on the form.  
Select ..., UnitPrice, Quantity, UnitPrice * Quantity AS ExtendedPrice
From ...;

If you insist on doing this in the form (against expert advice) then you have to worry about when to do the calculation.  You either have to do it in both the AfterUpdate event of the UnitPrice and Quantity fields or you would do it in the BeforeUpdate event of the Form.

Me.txtExtendedPrice = Me.txtUnitPrice * Me.txtQuantity
