W2 has 3 rows for Boxes 18-20. Box 20 has the same value . Box 18 has 2 rows with same value. It's not allowing me to proceed, Box 20 locality should appear only once?

I can't collapse the 3 rows into 1 as Box 18 shows different values.

it does not work. I already have the 3 rows. The issue is that Box 20 is the same for 3 rows.

Box 18 has same $ amt for 2 rows and different for the third, so i can't collapse all 3 rows into one or keep them separate. Turbotax allows only unique values in Box 20.

If you only worked in one location for your employer there should only be one entry for the line with boxes 18-20.  Line 20 having the same value would indicate that all 3 lines refer to the same locality.  If that is the case then you could add the lines for each box into a single line to enter into your tax return. 

 You should contact your employer to verify if this is true before entering a combined single entry. 

 This is not a problem with TurboTax as some taxpayers have wages earned in different localities while working for the same employer and each locality needs to be reported on a separate line to ensure proper credit.

Agree on adding all the lines. Issue is Row 3 has a amount for Box 18 that is different from Row 1 &2. I believe there is an error on the W2 and have reached out to my employer for clarification. Is it okay to submit for an extension so that this can be resolved. I doubt the employer will fix it in the next 2-3 days.

Yes, unless you are in OH, or a few of the areas that you can file your local return online, this will not affect your return so you can file with the local error.

However, if you are itemizing your return and it is duplicating taxes paid, you should leave the duplicated amount off your return so you do not get a deduction for the duplicated taxes.
