I only have one job/W2 and my federal withholding is higher than reported on my W2. Where did the other withholding come from? It won't add up now

I have to input the quarterly withholding.  But i only have the 1 W2 with an annual withholding.  This withholding is lower than what TurboTax says is being withheld.  Where did the other withholding come from?  I have a TD Ameritrade and Robinhood account, but I don't think they have done any withholding

If you entered no other tax documents with Federal tax withheld (like a Form 1099-G for example), then you should double-check your W-2 entry.  The withholding amount may have been entered incorrectly.  

Also, use the steps in the following TurboTax article to preview your Form 1040 to be sure that the amount you are seeing as withholding is not actually a payment applied from a previous year or some other type of tax payment reported on your return:
