Do property tax effect your federal tax return?

Looks like any number I put does not effect my federal tax due, however I though it did/should?

It really depends on where you are in putting in your income and deductions.

First, you need to get in all of your income...if you don't have that in, then deductions may not do anything.  You also must have enough income in such that you have some taxable income.

Then, the tax software first uses the allowable Standard Deduction for your filing status.....and you have to keep putting in all of your deductions, until the point is reached where your Itemized deductions exceed your Std Deduction....only then do more entries have an effect..so you just keep putting in your possible deductions.

Occasionally, your itemized deductions have started having an effect, but then putting in more stops having an effect....usually that occurs when your itemized deductions have reduced your taxable income to zero.  Putting in more deductions at that point don't do anything.  But i f you have more income to report come January or February  (w-2 forms and withholding), then, when that income is put in properly, there might be some other changes in your refund or balance due.

I fully understand, but that is not my case yet. my deductions are higher than the standard deductions but not by match. I have still have taxable income, thus it may be a bug in turbos tax at the moment

and note that not all deductions (such as Medical) count at 100%.

Two other aspects:

The deduction for real estate taxes is limited if your adjusted gross income (AGI) exceeds certain amounts.  See this IRS reference for details:  https://www.irs.gov/publications/p17/ch29.html#en_US_2013_publink1000300882

Also, you cannot deduct real estate taxes if you are subject to the Alternative Minimum Tax (AMT).  See this for more details on the AMT:  https://turbotax.intuit.com/tax-tools/tax-tips/IRS-Tax-Return/Alternative-Minimum-Tax--Common-Questi...

...........All valid points...the only way for you to know is to go up into "MyAccount" and then "Print Center" and print/save a copy to a PDF file (as it exists now) and look at your form 1040 and your Schedule A.

You will have to pay for the software to do that...and once paid, you cannot wipe your tax file with the "Clear and start over", but you can still edit everything at-will until you are ready to file next Feb or March..

And, as a final nit-picky point..
IF your "Taxable" income (line 43 of the form 1040) is between $3000 and $99,999 for ordinary income, and if the special situations commented above don't apply....then you have to remember that tax tables are used.  And those tax tables only change your taxes owed for every $50 change in your taxable income ( for any line 43 amounts $3000-to-$99,999).  So once you find the exact $1 point at which your taxes due (or refund) changes, then another $49 of deductions don't change anything...while $51 will.  Once you get above $100k of taxable income, then exact % values are used.  
(Below $3,000 of taxable income, the jumps occur at $15 or $25 income points...at least during 2015 they were).
