The 1099 G for Maryland has boxes 1-5, but the form on turbotax shows only Box 1, 4, 10a, 10b, 11. The number for federal tax is also the wrong box number what can I do?

Yes, the form 1099-G has many boxes.  The different parts of it are used in different sections of TurboTax.  You may not see all the box numbers in TurboTax each time a part of it is used in a section of the return.  The federal tax withheld should be for box 4 unless it is a different tax year form or a substitute form that does not match the box #s.  If it is a substitute form, but still for 2020, you can enter the federal withholding in the box labeled federal taxes withheld.

Since your 1099-G issued by Maryland only contains boxes 1-5, then it does contain the boxes applicable to reporting state unemployment compensation or a taxable prior year MD refund received.

For example, box 1 and 4 and 10a-11 would be used in the unemployment section of the return.

Boxes 2 and 3 would be used for reporting a taxable MD state refund.

Please review again the box for federal withholding.  It should be box 4 unless the tax reporting document is for a different year return or is a substitute form.

Be sure you are using a 2020 tax reporting document for a 2020 tax return.

I have read everything in this message string - and several other related ones - but have been completely unable to clear the "Needs Review" message for my 1099g for Maryland Unemployment. I have tried everything I can think of but the "Needs Review" message simply will not clear. I have probably tried 25 different solutions, including deleting the 1099g multiple times and re-entering, but to no avail. HELP?!?!?!?!
