I believe that form a would have more deductions than the standard deduction, can i get a copy of form a (itemized deductions) and how do i go about getting this form?

As you run through the Deductions and Credits tab, you're asked to provide everything that might appear on 1040 Schedule A.  When you're finished, TurboTax will inform you if you're better off itemizing (in which case a Schedule A will be generated) or taking the Standard Deduction (in which case it won't).  If you and your spouse are "married filing separately," you'll have to force both returns to either itemize or not.

You must mean a Schedule A.  That is where your itemized deductions appear.

STANDARD DEDUCTION

Many taxpayers are surprised this year because their itemized deductions are not having the same effect as they did on past tax returns.  The new higher standard deduction and the elimination of certain deductions, as well as the cap on state and local taxes have had a major impact.

Your itemized deductions have to be more than your standard deduction before you will see a change in your tax owed or tax refund.  The deductions you enter do not necessarily count “dollar for dollar;” many of them are subject to meeting  tough thresholds—medical expenses, for example, must meet a threshold that is pretty hard to reach.  The software program uses all the IRS rules that apply to the expenses you enter, and it tells you if you have enough to use your itemized deductions or if using the standard deduction is more advantageous for you.  Under the new tax laws, some deductions have been capped—there is a $10,000 limit to the itemized deductions for state, local, property and sales taxes.

Your standard deduction lowers your taxable income.  It is not a refund
