How to change value from first line in one newly added column

I have a file named file1.txt where below data is there

APPLICATION ODATE       IF_EXECUTING  APPLICATION_STATUS
Job1        20200731    Post          NOTOK
Job2        20200731    Post          NOTOK
Job3        20200731    Post          NOTOK
JOb3        20200731    Post          NOTOK
``````````````````````````````````````````````````````
Adding one new column using below command

awk -v column=4 -v value=”four” ‘BEGIN {FS = OFS = “ttt”;}{for ( i = NF + 1; i > column; i– ) {$i = $(i-1);}$i = value;print $0;}’ file1.txt


Output
`````````````````````````````````````````````````````````````````````````````````````````
APPLICATION ODATE       IF_EXECUTING  APPLICATION_STATUS                      four
Job1        20200731    Post          NOTOK                   four
JOb2        20200731    Post          NOTOK                   four
Job3        20200731    Post          NOTOK                   four
JOb4        20200731    Post          NOTOK                   four
`````````````````````````````````````````````````````````````````````````````````````````````

Here adding three "t" character. First line "four" should be spaced with APPLICATION_STATUS with just one t and first line "four" should be replaced with "CYCLE_NUMER"

Desired output
````````````````````````````````````````````````````````````````````````````````
APPLICATION ODATE       IF_EXECUTING  APPLICATION_STATUS    CYCLE_NUMBER
Job1        20200731    Post          NOTOK                 four
JOb2        20200731    Post          NOTOK                 four
Job3        20200731    Post          NOTOK                 four
JOb4        20200731    Post          NOTOK                 four
`````````````````````````````````````````````````````````````````````````````
