Hello David,
You first need to write CAML query to fetch data from SP list based on current user login. If one user can submit only one item in list then you can simply use below query to get item from list:
<Eq><FieldRef Name='Author'/><Value Type='Integer'><UserID Type='Integer'/></Value></Eq>
But if you can have multiple data in list then you also need to add one more condition in query to fetch correct item from list. I have used column name called "uniqueformcolumnname" so here you need to replace your column name and also need to pass value.
<Where>
<And>
<Eq>
<FieldRef Name="Author" />
<Value Type="Integer">
<UserID Type='Integer'/>
</Value>
</Eq>
<Eq>
<FieldRef Name="uniquecolumnname" />
<Value Type="Text">
//pass unique value here
</Value>
</Eq>
</And>
</Where>
Now once your query done then you can use below code to bind product with checkbox:
