Can I use Authorize.net to takedeposit for service call, The deposit is accepted by serviceman when at customer house using tablet with jot form

You can indeed use Authorize.net to take deposit. I checked your form it appears that you have already added the authorize.net payment integration to your form. You can finish the configuration of the payment module by clicking the wand icon as seen below.

Make sure that you have the correct credentials, then use Collect Donations/Custom Amount Payments.

Here are a couple of guides that can help you set it up:
