There may be some others, but the main error is on this line: 
return @{ $ar1 }, @{ $ar2 }, @{ $ar3 };

If you do that, all the values are flattened into a single array. You should return the array references, not the arrays: 
return ($ar1, $ar2, $ar3);

Of course, the calling routine has to be adapted to receive array refs, not arrays. In this case I do not see the usefulness of the data subroutine (unless I missed something). But if you want to keep it, let it also return array refs.

Basically, the whole thing could probably be rewritten as this (untested): 

#!/usr/bin/perl

use strict;
use warnings;

use Data::Dumper;

my ($test_a, $test_b, $test_c) = get_data();

print Dumper $test_a;
print Dumper $test_b;
print Dumper $test_c;

sub get_data{

     my ($ar1, $ar2, $ar3);


     push @$ar1,   ["Acc #", "Name", "Date", "House Number",],
        ["1235456", "Joe More", "03/07/2010", "5",],;  
    
     push @$ar2,  ["", "", "","",],
          ["Home ", "Year", "City","",],
          ["", "", "","",],
             ["1", "2000", "Local 1","",],
                ["2", "2001", "Local 2 ","",],
                ["3", "2002", "Local 3 ","",],
                ["4", "2003", "Local 4 ","",],
                ["5", "2014", "TLocal 5 ","",],
          ["", "", "","",],;
        
     push @$ar3, ["", "", "","",],
        ["Operation:", "", "","",],
        ["", "", "","Name","Place", "LOC", "REF","A#1","B#2", "C#3", "
+D#4",],
        ["", "", "","","", "", "","","", "", "",],
        ["", "", "","1","Mary L", "5/15/1940", "S","V","P", "-", "-",]
+,
        ["", "", "","2","Joe T", "6/8/1990", "B","Q","X", "-", "-",],
        ["", "", "","3","Carl C", "07/5/1288", "A","S","Y", "-", "-",]
+,
        ["", "", "","","", "", "","","", "", "",],;

     return $ar1, $ar2, $ar3;
}

Update: OK, I wanted to explain too much, so that two others were faster than me by 2 minutes. ;-) Also added revised full program (untested).
