Note: if your <$list> widget just used the default "currentTiddler"
variable, then you could simplify the above to:
<a href={{{ [{!!tracking_number}addprefix[https://tools.usps.com/go/
TrackConfirmAction_input?qtc_tLabels1=] }}
<https://tools.usps.com/go/TrackConfirmAction_input?qtc_tLabels1=]addsuffix%7B!!tracking_number%7D]%7D%7D>
}>USPS Tracking</a>
or, if you prefer:
<a href={{{ [[https://tools.usps.com/go/TrackConfirmAction_input?
qtc_tLabels1=]addsuffix{!!tracking_number}] }}
<https://tools.usps.com/go/TrackConfirmAction_input?qtc_tLabels1=]addsuffix%7B!!tracking_number%7D]%7D%7D>
}>USPS Tracking</a>
and, if you do want to use the "item" variable, you could still write one
of the above... just wrap the whole thing inside a <$tiddler> widget, like
this:
<$tiddler tiddler=<item>>
<a href={{{ [[https://tools.usps.com/go/TrackConfirmAction_input?
qtc_tLabels1=]addsuffix{!!tracking_number}] }}}>USPS Tracking</a>
</$tiddler>
